【摘要】 <正>在BCl₃样品中,常常混有COCl₂杂质.用通常的化学方法很难提纯.近年来,J.A.Merritt等巧妙地用CO₂激光辐照这些样品,仅照射几秒钟,由于BCl₃的红外敏化作用,COCl₂杂质就迅速被分解.这是利用激光提纯化学试剂的一个很成功的例子.我们研究了CO₂激光辐照BCl₃-C₃H₇Br体系.正溴丙烷在CO₂分子00°1～10°0跃迁的P支频率范围内,没有吸收带,不发生多光子解离.但是,当加入一定量的BCl₃以后,C₃H₇Br很容易裂解.我们对这一现象进行了初步探讨.更多还原

【Abstract】 1-bromopropane has no adsorption band in the frequency range corresponding to the p-branch of 001~100 transition of CO2 molecular, so that multiphoton dissociation does not occur. However, as a certain quantity of boron trichloride is added ,1-bromopropane will dissociate easily.更多还原
